Description

Technical Field

[0001] This application relates to the field of wearable device technology, and in particular to a smart glasses. Background Technology

[0002] With the continuous advancement of technology, the function of glasses is no longer limited to correcting vision and protecting the eyes. Today, smart glasses with photography and display functions are gradually emerging, bringing new experiences and convenience to people's lives.

[0003] In related technologies, smart glasses mainly consist of a frame and temples. The temples are rotatably connected to the frame, allowing them to fold and unfold flexibly for easy carrying and storage. For stable opening and closing, the temples need to have appropriate damping force during rotation. Furthermore, the frame of smart glasses is often quite heavy due to the various components it houses. To ensure a secure fit, the smart glasses also need to exert appropriate clamping force on the user's head through the temples.

[0004] However, in related technologies, the control of damping force and clamping force of smart glasses is prone to mutual interference, making it difficult to control the damping force and clamping force of smart glasses. Utility Model Content

[0005] This application provides a smart glasses solution that allows for relatively easy adjustment of the damping force and clamping force of the smart glasses.

[0006] This application provides a smart glasses system, comprising a frame, temples, a first connector, a rotating member, a second connector, and an elastic member. The first connector is fixedly connected to the frame. The rotating member includes a first rotating connecting portion, a second rotating connecting portion, and a limiting portion. The rotating member is rotatably connected to the first connector via the first rotating connecting portion, and can rotate relative to the first connector around a first axis between a folded position and an unfolded position. The limiting portion abuts against the first connector when the rotating member is in the unfolded position. The second connector is rotatably connected to the rotating member via the second rotating connecting portion, and can rotate relative to the rotating member from an initial position to an outward folding direction around a second axis. The first axis and the second axis are parallel or coincident. The temples are fixedly connected to the second connector. The elastic member is disposed between the second connector and the rotating member, and provides a restoring force to return the second connector to its initial position after the second connector rotates from its initial position to the outward folding direction.

[0007] The smart glasses provided in this application embodiment are rotatably connected to a first connecting member via a first rotating connecting part, allowing the temples to rotate around a first axis between a folded position and an unfolded position to realize the opening and closing function of the smart glasses. The structure between the first rotating connecting part and the first connecting member provides damping force for the temple rotation. When the rotating member is in the unfolded position, the limiting part abuts against the first connecting member, and the second connecting member can rotate around a second axis from its initial position in an outward folding direction. The elastic member provides a restoring force for the second connecting member to return to its initial position, so that the temples generate an appropriate clamping force on the user's head, achieving separation of the damping force and clamping force of the smart glasses. This facilitates the control of the damping force and clamping force of the smart glasses to specified values, improving user comfort. Furthermore, after unfolding, the temples can be further adjusted in angle to accommodate users with different head circumferences, thereby improving the adaptability of the smart glasses.

[0008] In one possible implementation, the elastic element is a torsion spring, which abuts against the second connecting element and the rotating element.

[0009] In this implementation, the torsion spring abuts against the second connector and the rotating component, so that the torsion spring provides a restoring force for the second connector to return to its initial position. In addition, the torsion spring itself occupies little space, which helps to reduce the overall size of the smart glasses, making them lighter and more portable.

[0010] In one possible implementation, the rotating component further includes a positioning post, with a torsion spring sleeved on the outside of the positioning post.

[0011] In this implementation, the torsion spring is sleeved on the outside of the positioning post, thus positioning the torsion spring and facilitating its installation. Furthermore, the positioning post limits the torsion spring's movement; during the rotation of the second connector, the torsion spring deforms, providing a restoring force for the second connector's repositioning.

[0012] In one possible implementation, the torsion spring includes a helical segment, a first end arm segment, and a second end arm segment, which are respectively connected to the two ends of the helical segment. The helical segment is sleeved on the outside of the positioning post and abuts against the positioning post, while the first end arm segment and the second end arm segment abut against the second connecting member.

[0013] In this implementation, the helical segment of the torsion spring is fixed on the outside of the positioning post. The first end arm segment and the second end arm segment abut against the second connector. During the rotation of the second connector, the second connector drives the first end arm segment and the second end arm segment to move, so that the first end arm segment and the second end arm segment are displaced relative to the helical segment, thereby deforming the torsion spring and providing a restoring force for the reset of the second connector.

[0014] In one possible implementation, the second connector has a first limiting groove and a second limiting groove. A first end arm segment passes through the first limiting groove and abuts against the groove wall of the first limiting groove, and a second end arm segment passes through the second limiting groove and abuts against the groove wall of the second limiting groove.

[0015] In this implementation, the first end arm segment is located in the first limiting groove, and the second end arm segment is located in the second limiting groove, thereby connecting the torsion spring and the second connecting member. This allows the second connecting member to drive the first end arm segment and the second end arm segment to move relative to the helical segment, causing the torsion spring to deform.

[0016] In one possible implementation, the second connector also has a clearance opening. The positioning post and the spiral section pass through the clearance opening, and both the first limiting groove and the second limiting groove communicate with the clearance opening.

[0017] In this implementation, the positioning post and the spiral segment pass through the clearance opening, which shortens the distance between the rotating part and the second connecting part. This helps to reduce the length and weight of the hinge assembly, and further improves the user's wearing comfort.

[0018] In one possible implementation, one end of the positioning post is connected to the first rotating connection. The surface of the second connector away from the first rotating connection has a first limiting groove and a second limiting groove.

[0019] In this implementation, the positioning post is connected to the first rotating connection, and the first limiting groove and the second limiting groove are located on the side surface of the second connector away from the first rotating connection, so that the positioning post extends as far as possible into the clearance opening, which helps to reduce the distance between the rotating member and the second connector, thereby reducing the length of the hinge assembly.

[0020] In one possible implementation, the smart glasses also include a limiting member. One end of the positioning post is connected to the first rotating connection, the limiting member is fixedly connected to the other end of the positioning post, and a torsion spring is disposed between the first rotating connection and the limiting member. The limiting member is used to abut against the end of the torsion spring away from the first rotating connection.

[0021] In this implementation, the limiting member is connected to the positioning post, and the position of the torsion spring is restricted by the limiting member, which effectively prevents the torsion spring from falling off the positioning post and improves the reliability of the structure.

[0022] In one possible implementation, the rotating member further includes a limiting platform portion disposed between the positioning post portion and the first rotating connection portion. One end of the positioning post portion is connected to the first rotating connection portion through the limiting platform portion. A torsion spring is disposed between the limiting platform portion and the limiting member. The limiting platform portion is used to abut against the end of the torsion spring away from the limiting member.

[0023] In this implementation, the torsion spring is clamped between the limiting platform and the limiting component, which further ensures the stability of the torsion spring installation.

[0024] In one possible implementation, the second rotating connection includes one of an arc-shaped groove and an arc-shaped arm, and the second connector is provided with the other of the arc-shaped groove and the arc-shaped arm. The arc-shaped arm passes through the arc-shaped groove and slides in cooperation with the groove wall of the arc-shaped groove. The second connector is rotatably connected through the arc-shaped groove and the arc-shaped arm.

[0025] In this implementation, the second connector and the rotating component are rotatably connected through the cooperation of an arc-shaped groove and an arc-shaped arm, enabling relative sliding between the second connector and the rotating component. The second axis between the second connector and the rotating component is a virtual axis, allowing the second connector to be closer to the first axis, thereby reducing the volume of the rotating component and making the smart glasses lighter.

[0026] In one possible implementation, the arc-shaped groove includes a first end located at one end in the extending direction of the arc-shaped groove, and the first end is a sealed structure. When the second connector is in the initial position, the end of the arc-shaped arm abuts against the first end.

[0027] In this implementation, the rotation direction of the second connector in its initial position can be limited by the first end, making the temples more stable when switching between the unfolded and folded states. Furthermore, it facilitates the adjustment of the initial restoring force of the elastic element.

[0028] In one possible implementation, the arc-shaped groove includes a second end located at one end of the extending direction of the arc-shaped groove, and the second end is an open structure.

[0029] In this implementation, the opening structure at the second end increases the range of motion of the arc-shaped arm and improves the adjustment angle range of the second connector relative to the rotating member.

[0030] In one possible implementation, the smart glasses also include a damping element. The damping element is located at the first rotating connection portion and is used to generate a damping force that resists relative rotation between the first connecting member and the rotating member.

[0031] In this implementation, the damping force generated by the damping element hinders the relative rotation between the rotating component and the first connecting component, ensuring smooth and slow movement when the temples close or open, preventing unwarranted loosening, and extending the service life of the hinge assembly. The damping element also facilitates the adjustment of the magnitude of the generated damping force.

[0032] In one possible implementation, the first rotating connection portion has a connecting hole extending through it, and the first connecting member is provided with a pin, which passes through the connecting hole. The rotating member is rotatably connected to the connecting hole via the pin. A damping member is disposed between the pin and the first rotating connection portion, and abuts against both the pin and the first rotating connection portion.

[0033] In this implementation, a damping element is positioned between the pin and the first rotating connection, abutting against both to generate appropriate damping force. This provides suitable resistance to the rotating component during rotation, slowing its rotation speed and preventing it from rapidly springing open or suddenly closing, thus improving stability and safety during use. Furthermore, the damping element helps maintain the stability of the rotating component's position after it has been adjusted to a suitable location.

[0034] In one possible implementation, the wall of the connecting hole has a receiving groove, in which at least a portion of the damping element is received, and the damping element abuts against the groove wall and the pin.

[0035] In this implementation, part of the damping element is housed within the receiving groove, making its connection more stable and less prone to displacement or loosening, thus ensuring the consistency and stability of the damping effect. Furthermore, the damping element abuts against the groove wall and the pin, allowing for more precise control of the relative rotation between the rotating component and the first connecting component, further enhancing the damping effect.

[0036] In one possible implementation, the receiving groove extends through at least one side surface of the first rotating connection along the extension direction of the centerline of the connecting hole.

[0037] In this implementation, the receiving groove extends through at least one side of the surface of the first rotating connection portion, so that the damping element can be installed between the pin and the first rotating connection portion.

[0038] In one possible implementation, the damping element includes a spring. The spring is disposed between the pin and the first rotating connection portion, and abuts against both the pin and the first rotating connection portion.

[0039] In this implementation, the spring abuts against both the pin and the first rotating connection, applying an initial elastic force to the pin to create a damping force for rotation between the first rotating connection and the pin. Furthermore, the damping force is provided by the initial elastic force of the spring, which facilitates setting the magnitude of the initial elastic force and altering the damping force for opening and closing the temple.

[0040] In one possible implementation, the smart glasses further include a first device, a second device, and a flexible connector. The first device is disposed on the frame, the second device is disposed on the temple, and the first and second devices are electrically connected by the flexible connector. The first rotating connection portion has a wiring channel, the two ends of which are angularly spaced around a first axis, and both ends of the wiring channel communicate with the space outside the rotating component. The flexible connector passes through the wiring channel.

[0041] In this implementation, the wiring channel within the first rotating connection portion, with its two ends angularly spaced along the first axis and connected to the external space, provides a concealed and convenient wiring path for the flexible connector. The flexible connector passes through the wiring channel and is electrically connected to the first and second devices, thus realizing the electrical connection between the frame and the devices on the temples of the smart glasses. Furthermore, it reduces exposed wiring, improves the overall aesthetics, makes the smart glasses look simpler, and reduces the risk of damage to the wiring during use.

[0042] In one possible implementation, the first connector includes a substrate portion and a connecting seat portion. One surface of the substrate portion in the thickness direction is connected to the frame, and the connecting seat portion is disposed on the other surface of the substrate portion in the thickness direction, forming an assembly space. A first rotatable connector is rotatably connected to the connecting seat portion within the assembly space. One end of a wiring channel communicates with the assembly space, and the other end of the wiring channel communicates with the space outside the connecting seat portion. The substrate portion has a wiring opening that communicates with the assembly space, and a flexible connector passes through the assembly space and the wiring opening.

[0043] In this implementation, the connector is located on one side surface of the substrate in the thickness direction to improve connection strength. One end of the wiring channel communicates with the assembly space, and the other end communicates with the outer space of the connector. The substrate also has a wiring port communicating with the assembly space, achieving a concealed arrangement of the flexible connector. This enhances the overall aesthetics, making the smart glasses appear more streamlined. Attached Figure Description

[0059] The terminology used in the implementation section of this application is only for explaining specific embodiments of this application and is not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0060] This application provides a smart glasses embodiment. The smart glasses may include, but are not limited to, augmented reality (AR) smart glasses, virtual reality (VR) smart glasses, mixed reality (MR) smart glasses, and movie-watching glasses.

[0061] Figure 1 This is a schematic diagram of the structure of a smart glasses provided in an embodiment of this application.

[0062] like Figure 1 As shown in the embodiment of this application, the smart glasses include a lens 100 and a frame, with the lens 100 disposed on the frame.

[0063] In some examples, there are two lenses 100, which are spaced apart on the frame along the length of the frame. When the smart glasses are worn on the user's head, the two lenses 100 are located in front of the user's left and right eyes, respectively.

[0064] In some other examples, there may be only one lens 100. When the smart glasses are worn on the user's head, the lens 100 may be located in front of the user's left and right eyes. That is, the lens 100 located in front of the user's left and right eyes is the same lens 100.

[0065] For example, lens 100 can be an optical waveguide lens, so that lens 100 can be used to display images.

[0066] like Figure 1 As shown in this embodiment, the eyeglass frame includes a frame 200, temples 300, and a hinge assembly 400. The temples 300 are rotatably connected to the frame 200 via the hinge assembly 400.

[0067] For example, smart glasses may include two temples 300 and two hinge assemblies 400, with the two temples 300 respectively disposed at both ends of the frame 200 via a hinge assembly 400, and the lens 100 disposed inside the frame 200.

[0068] For example, the temple 300 has a connecting end and a free end. The connecting end is rotatably connected to the frame 200 via a hinge assembly 400, while the free end is not connected to the frame 200.

[0069] For example, the temple 300 has an unfolded state (e.g. Figure 1(As shown in the diagram) and folded state. When the temples 300 are in the unfolded state, the free ends of the temples 300 are away from the frame 200, making it easier for the user to wear the smart glasses on their head. At this time, the two temples 300 contact the sides of the user's head and hang above the user's ears. When the temples 300 change from the unfolded state to the folded state, the two temples 300 rotate towards each other, and the free ends of the temples 300 move closer to or contact the frame 200, thus folding onto the frame 200, making the smart glasses easier to store and carry.

[0070] For example, the smart glasses also include a first device, a second device, and a flexible connector. The first device is disposed on the frame 200, and the second device is disposed on the temple 300. The first device and the second device are electrically connected via the flexible connector. The flexible connector is used to maintain the electrical connection between the first device and the second device when the temple 300 is in a folded or unfolded state, ensuring the normal use of the device.

[0071] In some examples, the first device can be a display device or a camera. The display device (e.g., an optical engine) can be used to project images and other information onto the lens 100, and the camera can be used to capture images. The second device can be a processing device, such as a motherboard.

[0072] In other examples, the first device can also be an interactive device, such as a touch sensor, and the second device can be a processing device, allowing the user to control the glasses' functions by touching or swiping the touch sensor. For example, the user can adjust the volume, switch the displayed content, etc. by touching or swiping the touch sensor.

[0073] In other examples, the first device can be a processing device, and the second device can be an interaction device.

[0074] For example, each of the two temples 300 is provided with a second device, and the two second devices are electrically connected to the first device through flexible connectors.

[0075] In some examples, the flexible connector can be a flexible printed circuit (FPC). The flexible printed circuit passes through the hinge assembly 400 and is electrically connected to the first and second devices, respectively.

[0076] In other examples, the flexible connector can also be a cable.

[0077] Because smart glasses frames often contain one or more primary components, the frame area is frequently quite heavy, making them more prone to loosening or slipping during wear. To improve the stability of smart glasses, the temples need to exert appropriate clamping force on the user's head when worn. Furthermore, for stable opening and closing of the temples, they need to have appropriate damping force when rotating.

[0078] In related technologies, the temples and frames are rotatably connected by a pivot. The damping force and clamping force of smart glasses both depend on the specific structure at the same pivot, making it easy for the control of the damping force and clamping force of smart glasses to affect each other, which makes it difficult to control the damping force and clamping force of smart glasses.

[0079] Figure 2 This is a schematic diagram of a hinge assembly provided in an embodiment of this application.

[0080] like Figure 2 As shown, based on this, in this embodiment of the application, the hinge assembly 400 includes a first connector 410, a rotating member 420, and a second connector 430. The first connector 410 is fixedly connected to the frame 200, and the second connector 430 is fixedly connected to the temple 300. The first connector 410 is rotatably connected to the rotating member 420, and the second connector 430 is rotatably connected to the rotating member 420.

[0081] Figure 3 for Figure 2 A cross-sectional schematic diagram of the hinge assembly provided in the document. Figure 4 for Figure 2 Exploded view of the structure of the central hinge assembly.

[0082] like Figure 3 and Figure 4 As shown, for example, the rotating member 420 includes a first rotating connecting portion 421 and a second rotating connecting portion 422. The rotating member 420 is rotatably connected to the first connecting member 410 through the first rotating connecting portion 421. The rotating member 420 can be positioned relative to the first connecting member 410 about a first axis in an unfolded position (e.g., Figure 2 The rotating member 420 rotates between the folded and unfolded positions (as shown in the diagram). The folded and unfolded positions are relative to the first connecting member 410. When the rotating member 420 rotates between the folded and unfolded positions, it drives the second connecting member 430 and the temple 300 to rotate. When the rotating member 420 rotates to the unfolded position, the temple 300 switches to the unfolded state. When the rotating member 420 rotates to the folded position, the temple 300 switches to the folded state.

[0083] The second connecting member 430 is rotatably connected to the rotating member 420 via the second rotating connecting part 422. After the rotating member 420 rotates to the unfolded position, the second connecting member 430 can rotate relative to the rotating member 420 around the second axis from the initial position (e.g., Figure 3 (as shown) outward turning direction (e.g.) Figure 3 Rotate in the direction indicated by the solid arrow in the middle.

[0084] In this application, the outward turning direction of the second connector 430 refers to the direction in which the second connector 430 drives the connected temple 300 to rotate away from the other temple 300.

[0085] In this way, the rotating member 420 is rotatably connected to the first connecting member 410 via the first rotating connecting part 421, allowing the temple 300 to rotate around the first axis to realize the opening and closing function of the temple 300. The structure between the first rotating connecting part 421 and the first connecting member 410 provides damping force for the rotation of the temple 300. The second connecting member 430 is rotatably connected to the rotating member 420 via the second rotating connecting part 422. The second connecting member 430 can rotate around the second axis from the initial position to the outward flipping direction. This allows the temple 300 to further flip outward after unfolding, causing the temple 300 to expand outward. The structure between the second rotating connecting part 422 and the second connecting member 430 provides clamping force, realizing the separation of the damping force and clamping force of the smart glasses. This helps to control the damping force and clamping force of the smart glasses to a specified value, improving the user's wearing comfort. In addition, the outward expansion of the temple 300 can also accommodate users with larger head circumferences, thereby improving the adaptability of the smart glasses. The opening angle of the temples 300 is adjusted to make it easier for users to put on and take off the smart glasses.

[0086] In this application, the "outward expansion" of the temple 300 refers to the rotation of the temple 300 in a direction away from each other after it is unfolded, so as to increase the distance between the two temples 300.

[0087] For example, the rotating component 420 is a one-piece molded part. This improves the manufacturing efficiency of the rotating component 420.

[0088] For example, the rotating component 420 can be a plastic part. This facilitates rapid manufacturing of the rotating component 420, reducing costs and the weight of the smart glasses.

[0089] For example, the rotating component 420 can also be a metal component. This helps to improve the strength and wear resistance of the rotating component 420 and increase the service life of the hinge assembly 400.

[0090] For example, the hinge assembly 400 also includes an elastic element disposed between the second connector 430 and the rotating member 420. The elastic element is used to provide a restoring force to return the second connector 430 to its initial position after the second connector 430 rotates from its initial position to the outward direction.

[0091] The restoring force provided by the elastic element allows the temple 300 to better fit the user's head, making it easier to wear, reducing the possibility of the glasses loosening or slipping, and improving user comfort. Furthermore, the elastic element provides a restoring force to the outward folding of the second connector 430, enabling the temple 300 to have a clamping force. The restoring force of the second connector 430 is separated from the damping force between the first connector 410 and the first rotating connection 421, allowing for control of the magnitude of the restoring force of the second connector 430, ensuring an appropriate clamping force of the temple 300 and improving user comfort. In addition, the basic opening and closing function of the temple 300 is achieved through the relative rotation of the first connector 410 and the rotating member 420. During the opening and closing process of the temple 300, the second connector 430 rotates and opens / closes along with the rotating member 420, thus making the smart glasses smaller when folded.

[0092] For example, the first axis coincides with the second axis. After the first axis and the second axis coincide, the rotating member 420 and the connecting member can be integrated more compactly, saving space and making the overall structure of the glasses more compact.

[0093] In other examples, the first axis is parallel to the second axis. The first axis and the second axis are parallel but do not coincide, which allows the rotational positions of the first connector 410 and the second connector 430 to be separated, making the connection between the first connector 410 and the second connector 430 and the rotating member 420 more flexible.

[0094] For example, the rotating member 420 also includes a limiting part 423. The limiting part 423 is used to abut against the first connecting member 410 when the rotating member 420 is in the unfolded position. When the rotating member 420 rotates to the unfolded position, the limiting part 423 abuts against the first connecting member 410 to limit the continued rotation of the first rotating connecting part 421 and limit the rotating member 420 to the unfolded position. When it is necessary to further open the temple 300, the second connecting member 430 rotates on the second rotating connecting part 422 to realize the continued outward expansion of the temple 300 on the second connecting member 430, and the clamping force is provided by the elastic member, realizing the separation of the outward expansion of the temple 300 and the opening action of the temple 300. This allows the damping force and clamping force of the smart glasses to be generated in stages, so that the damping force and clamping force of the smart glasses are separated, and the clamping force of the temple 300 can be adjusted by the elastic member to improve the user's wearing comfort.

[0095] For example, the damping force between the first rotating connection 421 and the first connector 410 can be less than the force that causes the elastic member to deform, so that the second connector 430 can be kept in the initial position when the temple 300 switches between the unfolded state and the folded state.

[0096] In some examples, the elastic element is a torsion spring 440, which abuts against the second connector 430 and the rotating member 420. When the second connector 430 rotates relative to the rotating member 420 about a second axis, the torsion spring 440 between the second connector 430 and the rotating member 420 deforms, exhibiting a tendency to drive the second connector 430 back to its initial position, thus providing a restoring force to return the second connector 430 to its initial position. Furthermore, the torsion spring 440 itself occupies a small space, helping to reduce the overall size of the smart glasses, making them lighter and more portable.

[0097] In other examples, the elastic element may include a spring, a sheet, etc.

[0098] like Figure 4 As shown, exemplarily, the rotating member 420 also includes a positioning post 424, and a torsion spring 440 is sleeved on the outside of the positioning post 424. The positioning post 424 is located on the first rotating connecting part 421, and the torsion spring 440 is sleeved on the positioning post 424, and then abuts against the second connecting member 430 and the rotating member 420 respectively. The positioning post 424 plays a role in fixing and limiting the torsion spring 440, which can effectively reduce the possibility of the torsion spring 440 deviating from its position during use, and at the same time provide precise positioning for the installation of the torsion spring 440, facilitating the installation operation of the torsion spring 440.

[0099] For example, the central axis of the positioning post 424 is perpendicular to the rotation axis of the first rotating connection 421. This ensures that when the torsion spring 440 is fitted onto the positioning post 424, its central axis is perpendicular to both the first and second axes. This allows the torsion spring 440 to deform when the second connector 430 rotates relative to the rotating member 420, providing a restoring force for the second connector 430 to return to its initial position.

[0100] like Figure 4As shown, exemplarily, the rotating member 420 further includes a limiting platform 425 disposed between the positioning post 424 and the first rotating connection 421. One end of the positioning post 424 is connected to the first rotating connection 421 via the limiting platform 425. The limiting platform 425 is fixed to the first rotating connection 421, and the positioning post 424 is fixedly connected to the end of the limiting platform 425 away from the first rotating connection 421. The limiting platform 425 is used to abut against the end of the torsion spring 440 away from the limiting member 450. The side of the limiting platform 425 away from the first rotating connection 421 abuts against the torsion spring 440 to limit the position of the torsion spring 440, effectively reducing the possibility of the torsion spring 440 deviating from its position during use.

[0101] For example, the limiting platform 425 can be a frustum, and the diameter of the limiting platform 425 is larger than the diameter of the limiting post, so that the torsion spring 440 sleeved on the positioning post 424 abuts against the limiting platform 425.

[0102] For example, the limiting platform 425 can also be a rectangular platform. The side area of ​​the limiting platform 425 away from the first rotating connection 421 is larger than the cross-sectional area of ​​the positioning column 424 in the direction perpendicular to the axis, so that the torsion spring 440 sleeved on the positioning column 424 abuts against the limiting platform 425.

[0103] like Figure 4 As shown, exemplarily, the smart glasses also include a limiting member 450. One end of the positioning post 424 is connected to the first rotating connection 421, and the limiting member 450 is fixedly connected to the other end of the positioning post 424. A torsion spring 440 is disposed between the first rotating connection 421 and the limiting member 450, and the limiting member 450 abuts against the end of the torsion spring 440 away from the first rotating connection 421. The limiting member 450 effectively prevents the torsion spring 440 from falling off the positioning post 424, improving the reliability of the structure.

[0104] In the example where the rotating member 420 has a limiting platform 425, a torsion spring 440 is sleeved on the positioning post 424. The torsion spring 440 is located between the limiting platform 425 and the limiting member 450, with both sides of the torsion spring 440 abutting against the limiting platform 425 and the limiting member 450, respectively. The position of the torsion spring 440 is limited by the limiting platform 425 and the limiting member 450, preventing the torsion spring 440 from deviating from its position during use.

[0105] In some examples, the limiting platform 425 and the limiting member 450 can also clamp and fix the torsion spring 440 to improve the fixing effect of the torsion spring 440.

[0106] For example, the limiting member 450 can be a pressure plate. The pressure plate is fixed to the positioning post 424 to limit the torsion spring 440 between the first rotating connection 421 and the limiting member 450.

[0107] For example, the hinge assembly 400 may also include a first fastener 470 that secures the limiting member 450 to the positioning post 424.

[0108] For example, the first fixing member 470 can be a screw. Correspondingly, the first fixing member 470 has a through hole, and the end of the positioning post 424 away from the first rotating connection part 421 has a bolt hole. The screw passes through the through hole of the first fixing member 470 and is threaded into the bolt hole on the positioning post 424 to fix the first fixing member 470 to the positioning post 424.

[0109] In the example where the first fastener 470 is a screw, the screw can also be a locking screw, which has a self-locking function to prevent the screw from loosening and improve the stability of the connection of the limiting member 450.

[0110] In some other examples, the first fastener 470 can also be a rivet. The rivet passes through the first fastener 470 and is riveted to the positioning post 424 to secure the limiting member 450.

[0111] For example, the torsion spring 440 includes a helical segment 441, a first end arm segment 442, and a second end arm segment 443, which are respectively connected to the two ends of the helical segment 441. The helical segment 441 is sleeved on the outside of the positioning post 424 and abuts against the positioning post 424. The first end arm segment 442 and the second end arm segment 443 abut against the second connecting member 430. During the rotation of the second connecting member 430, the second connecting member 430 drives the first end arm segment 442 and the second end arm segment 443 to move, so that the first end arm segment 442 and the second end arm segment 443 are displaced relative to the helical segment 441, thereby deforming the torsion spring 440 and providing a restoring force for the reset of the second connecting member 430.

[0112] In some examples where the rotating member 420 has a limiting platform 425, the helical segment 441 abuts against the limiting platform 425 on the side near the first rotating connection 421.

[0113] In some examples where the hinge assembly 400 has a limiting member 450, the side of the helical segment 441 away from the first rotating connection 421 abuts against the limiting member 450.

[0114] Figure 5 for Figure 2 A schematic diagram of the hinge assembly provided in the image from another perspective.

[0115] like Figure 4 and Figure 5 As shown, exemplarily, the hinge assembly 400 also includes a second fastener 480, through which the temple 300 is fixed to the second connector 430.

[0116] For example, the second fastener 480 can be a screw, and the second connector 430 has a threaded hole that matches the second fastener 480. The second fastener 480 passes through the temple 300 and is threadedly connected to the threaded hole to achieve a fixed connection between the second connector 430 and the temple 300.

[0117] For example, the temple 300 can also be bonded and fixed to the second connector 430.

[0118] like Figure 4 and Figure 5 As shown, exemplarily, the second connector 430 has a first limiting groove 431 and a second limiting groove 432. A first end arm segment 442 passes through the first limiting groove 431 and abuts against the groove wall of the first limiting groove 431, while a second end arm segment 443 passes through the second limiting groove 432 and abuts against the groove wall of the second limiting groove 432. When installing the torsion spring 440, the first end arm segment 442 is placed in the first limiting groove 431, and the second end arm segment 443 is placed in the second limiting groove 432, thus connecting the torsion spring 440 to the second connector 430. This allows the second connector 430 to move the first end arm segment 442 and the second end arm segment 443 relative to the helical segment 441, causing the torsion spring 440 to deform.

[0119] For example, the second connector 430 also has a clearance opening 433. The positioning post 424 and the helical segment 441 pass through the clearance opening 433, and the first limiting groove 431 and the second limiting groove 432 are both connected to the clearance opening 433. The helical segment 441 of the torsion spring 440 is located in the clearance opening 433. The first end arm of the torsion spring 440 passes through the clearance opening 433 and into the first limiting groove 431, abutting against the groove wall of the first limiting groove 431. The second end arm segment 443 of the torsion spring 440 passes through the clearance opening 433 and into the second limiting groove 432, abutting against the groove wall of the second limiting groove 432, so as to connect the second connector 430 and the rotating member 420 through the torsion spring 440. The deformation of the torsion spring 440 provides a restoring force for the second connector 430 to return to its original position.

[0120] In some examples where the hinge assembly 400 has a limit member 450, the limit member 450 may also be located within the clearance opening 433.

[0121] In some examples where the hinge assembly 400 has a first fastener 470, the first fastener 470 may also be located within the clearance opening 433.

[0122] In some examples where the rotating member 420 has a limiting platform 425, the limiting platform 425 may also be partially located within the clearance opening 433.

[0123] The clearance opening 433 accommodates structures such as the helical segment 441 and the positioning post 424, providing space for displacement or deformation. This allows for relative rotation between the second connector 430 and the rotating member 420. Furthermore, it shortens the distance between the rotating member 420 and the second connector 430, which helps reduce the length and weight of the hinge assembly 400, further improving user comfort.

[0124] For example, the clearance 433 is provided in the middle of the second connector 430 and extends through the second connector 430 along the axial direction of the positioning post 424.

[0125] For example, the clearance 433 also extends through the second connector 430 in a direction opposite to the outward turning direction to provide displacement or deformation space for structures such as the positioning post 424 and the helical segment 441.

[0126] For example, the first limiting groove 431 is located on the upper part of the second connector 430, and the second limiting groove 432 is located on the lower part of the second connector 430. The clearance opening 433 is located between the first limiting groove 431 and the second limiting groove 432 and communicates with the second limiting groove 432 in the first limiting groove 431. That is, the first limiting groove 431 penetrates the upper part of the second connector 430 near the lower part of the second connector 430, and the second limiting groove 432 penetrates the lower part of the second connector 430 near the upper part of the second connector 430, so as to allow the first end arm segment 442 of the torsion spring 440 to be inserted into the first limiting groove 431 and the second end arm segment 443 to be inserted into the second limiting groove 432.

[0127] In this application, the "upper part" of the second connector 430 refers to the part of the second connector 430 that is away from the ground when the smart glasses are worn on the user's head, the "lower part" of the second connector 430 refers to the part of the second connector 430 that is close to the ground when the smart glasses are worn on the user's head, and the "middle part" of the second connector 430 refers to the part between the upper and lower parts of the second connector 430.

[0128] For example, the first limiting groove 431 also extends through the upper part of the second connector 430 away from the lower part of the second connector 430, and the second limiting groove 432 also extends through the lower part of the second connector 430 away from the upper part of the second connector 430.

[0129] For example, the first limiting groove 431 and the second limiting groove 432 are located on the side surface of the second connector 430 away from the first rotating connection portion 421, so as to reduce the distance between the rotating member 420 and the second connector 430, thereby reducing the length of the hinge assembly 400.

[0130] For example, the second connector 430 is provided with an abutment portion located on the side of the second connector 430 near the first rotating connecting portion 421. The abutment portion is used to abut against the first connector 410 after the second connector 430 rotates outward from its initial position by a certain angle, to prevent the temple 300 from over-expanding, which could lead to excessive deformation of the torsion spring 440 and make it difficult to return to its original shape. When the second connector 430 is in its initial position, there is a gap between the abutment portion and the first connector 410. When the second connector 430 continues to expand outward until the abutment portion abuts against the first connector 410, it reaches its maximum outward expansion position.

[0131] In other examples, the torsion spring 440 may also have one of the first end arm segment 442 and the second end arm segment 443 abutting against the rotating member 420, and the other abutting against the second connecting member 430. When the second connecting member 430 rotates about the rotating member 420, the relative positions of the first end arm segment 442 and the second end arm segment 443 change, causing the torsion spring 440 to deform and provide a clamping force for the temple 300.

[0132] In some other examples, the torsion spring 440 is clamped between the rotating member 420 and the second connecting member 430. In this case, the rotating member 420 may not include the positioning post 424. When the second connecting member 430 rotates around the rotating member 420, it causes the torsion spring 440 to deform, providing a clamping force for the temple 300.

[0133] like Figure 3 and Figure 4 As shown, in some embodiments, the second rotating connection 422 includes an arc-shaped arm 4221, and the second connector 430 is provided with an arc-shaped groove 434. The arc-shaped arm 4221 passes through the arc-shaped groove 434 and slides in cooperation with the groove wall of the arc-shaped groove 434. The second connector 430 is rotatably connected to the arc-shaped groove 434 and the arc-shaped arm 4221. This enables relative rotation between the second connector 430 and the rotating member 420. The second axis between the second connector 430 and the rotating member 420 is a virtual axis, allowing the second connector 430 to be closer to the first axis, thereby reducing the volume of the rotating member 420 and making the smart glasses lighter.

[0134] In some embodiments, the axis of the arc arm 4221 is a second axis, which is parallel to the first axis.

[0135] In some other embodiments, the axis of the arc-shaped arm 4221 is a second axis, which coincides with the first axis. This allows the second connector 430 and the rotating member 420 to be arranged more compactly, reducing the volume of the hinge assembly 400.

[0136] For example, two arc-shaped arms 4221 are provided, and the two arc-shaped arms 4221 are respectively located on both sides of the positioning post portion 424. Similarly, two arc-shaped sliding grooves 434 are provided on the second connector 430, and the two arc-shaped sliding grooves 434 are respectively provided on the upper part and the lower part of the second connector 430, so that the two arc-shaped arms 4221 are slidably connected in the two arc-shaped sliding grooves 434, thereby improving the stability of the connection between the second connector 430 and the rotating member 420.

[0137] In some examples, the side of the arc-shaped groove 434 away from the positioning post 424 is a closed structure, and the side of the arc-shaped groove 434 near the positioning post 424 is an open structure. Two arc-shaped arms 4221 are slidably connected in the arc-shaped groove 434 and abut against the groove wall of the side of the arc-shaped groove 434 away from the positioning post 424, so as to support the arc-shaped arms 4221 by the groove wall of the side of the arc-shaped groove 434 away from the positioning post 424.

[0138] In some other examples, the side of the arc-shaped groove 434 near the positioning post 424 is an open structure, and the side of the arc-shaped groove 434 away from the positioning post 424 is a closed structure. Two arc-shaped arms 4221 are clamped on the two arc-shaped grooves 434 to realize the connection between the second connector 430 and the rotating member 420.

[0139] In some other embodiments, the second rotating connection part 422 includes an arc-shaped groove, and the second connector 430 is provided with an arc-shaped arm. The arc-shaped arm passes through the arc-shaped groove and slides in cooperation with the groove wall of the arc-shaped groove. The second connector is rotatably connected through the arc-shaped groove and the arc-shaped arm.

[0140] The arc-shaped groove 434 includes a first end and a second end, which are located at the two ends of the extension direction of the arc-shaped groove 434, respectively. Specifically, the first end is one end of the arc-shaped groove 434 in the outward turning direction, and the second end is one end of the arc-shaped groove 434 in the opposite direction to the outward turning direction.

[0141] In some examples, the first end is a closed structure. When the second connector 430 is in its initial position, the end of the arc-shaped arm 4221 abuts against the first end. When the second connector 430 rotates relative to the rotating member 420 from its initial position in the outward folding direction, the arc-shaped arm 4221 slides away from the first end. At this time, the rotation direction of the second connector 430 in its initial position can be limited by the first end, making the temple 300 more stable when switching between the unfolded and folded states. In addition, it is convenient to adjust the magnitude of the initial restoring force of the elastic member.

[0142] In some examples, the second end is an open structure, allowing the arc-shaped arm 4221 to pass through the arc-shaped groove 434 when the second connector 430 rotates outward relative to the rotating member 420 from its initial position. The open structure at the second end increases the range of motion of the arc-shaped arm 4221 and improves the adjustment angle range of the second connector 430 relative to the rotating member 420.

[0143] For example, the first rotating connection part 421 can be a rotating cylinder. The rotating cylinder is rotatably connected to the first connecting member 410. The second rotating connection part 422 is fixedly connected to the rotating cylinder.

[0144] For example, the positioning post 424 is fixed to the rotating drum by the limiting platform 425. The central axis of the positioning post 424 is perpendicular to the rotation axis of the rotating drum.

[0145] In some other examples, a pivot is provided on one of the second rotating connection 422 and the second connector 430, and the other is rotatably connected to the pivot.

[0146] Figure 6 for Figure 2 A schematic diagram of the structure of the first connector of the hinge assembly provided in the diagram.

[0147] like Figure 6 As shown, exemplarily, the first connector 410 includes a substrate portion 411. One surface of the substrate portion 411 in the thickness direction is connected to the frame 200. Specifically, the substrate portion 411 includes a first side surface and a second side surface, which are located on opposite sides of the substrate portion 411 in the thickness direction, and the first side surface is connected to the frame 200.

[0148] For example, the first connector 410 also includes a plug-in portion 413, which is fixed to the first side of the base plate portion 411 and is plugged into the mounting cavity corresponding to the end of the mirror frame 200 for fixed connection.

[0149] For example, the insertion part 413 is bonded to the corresponding mounting cavity of the frame 200.

[0150] In some other examples, the connector 413 can also be fixed to the frame 200 by snap-fit.

[0151] For example, the insertion part 413 includes a first plate and a second plate, both of which are fixed on the base plate part 411. The second plate and the second plate have an included angle for insertion and mating with the mounting cavity corresponding to the mirror frame 200.

[0152] For example, the first plate and the second plate are combined to form an L-shaped plate to improve the connection strength between the first connecting part and the frame 200.

[0153] For example, the first connector 410 further includes a connector seat 412, which is fixed to the second side of the base plate 411. That is, the connector seat 412 is located on the side of the base plate 411 away from the frame 200, and the connector seat 412 forms an assembly space. The first rotatable connector 421 is rotatably connected to the connector seat 412 within the assembly space.

[0154] For example, the first connector 410 is further provided with a pin 414, and the first rotating connection part 421 is rotatably disposed on the pin 414.

[0155] For example, the pin 414 is fixedly connected to the assembly space formed by the connecting seat portion 412, and the first rotating connecting portion 421 is rotatably sleeved on the pin 414. This enables relative rotation between the rotating member 420 and the first connecting member 410.

[0156] In other examples, the pin 414 may also be rotatably connected to the connecting seat 412 to form an assembly space, with the first rotatable connecting part 421 fixedly sleeved on the pin 414.

[0157] In some examples where the pin 414 is rotatably connected to the connecting seat 412 to form an assembly space, the tension between the pin 414 and the connecting seat 412 is adjusted by screws to provide damping force for the rotation of the pin 414, thereby providing damping force for the unfolding process of the temple 300.

[0158] For example, the first connector 410 is a one-piece molded part. This improves the manufacturing efficiency of the first connector 410.

[0159] For example, the first connector 410 can be a plastic part. This facilitates rapid manufacturing of the first connector 410, reducing costs and the weight of the smart glasses.

[0160] For example, the first connector 410 can also be a metal part. This helps to improve the strength of the first connector 410 and increase the service life of the hinge assembly 400.

[0161] For example, the first rotating connection portion 421 has a connecting hole 4211 passing through the first rotating connection portion 421, and a pin 414 passes through the connecting hole 4211. The rotating member 420 is rotatably connected to the connecting hole 4211 through the pin 414. The axis of the connecting hole 4211 coincides with the first axis.

[0162] Figure 7 for Figure 2 Another cross-sectional schematic diagram of the hinge assembly provided.

[0163] like Figure 7As shown, for example, the limiting part 423 is disposed on the rotating cylinder, and the connecting seat part 412 includes a mating part 4121. When the rotating member 420 is in the unfolded position, the limiting part 423 abuts against the mating part 4121 to limit the continued rotation of the first rotating connecting part 421, thus confining the first rotating connecting part 421 to the unfolded position. When it is necessary to further open the temple 300, the second connecting member 430 rotates on the second rotating connecting part 422 to achieve the continued outward expansion of the temple 300 on the second connecting member 430, thereby separating the outward expansion of the temple 300 from the opening action of the temple 300.

[0164] like Figure 7 As shown, exemplarily, the smart glasses also include a damping element 460. The damping element 460 is disposed on the first rotating connection portion 421 and is used to generate a damping force that hinders the relative rotation of the first connecting member 410 and the rotating member 420. The damping force generated by the damping element 460 hinders the relative rotation of the rotating member 420 and the first connecting member 410, making the temples 300 move smoothly and slowly when closing or opening, preventing the temples 300 from loosening unnecessarily, extending the service life of the hinge assembly 400. By providing the damping element 460, the magnitude of the generated damping force can be easily adjusted.

[0165] For example, the damping member 460 is disposed between the pin 414 and the first rotating connection portion 421, and abuts against the pin 414 and the first rotating connection portion 421 respectively.

[0166] In some examples, the damping element 460 is located within the connecting hole 4211, and the damping element 460 abuts against the hole wall of the connecting hole 4211 of the pin 414, providing damping force to the pin 414. In addition, the damping element 460 can also help maintain the stability of the position of the rotating element 420 after it has been adjusted to the appropriate position.

[0167] like Figure 7 As shown, exemplarily, the wall of the connecting hole 4211 has a receiving groove 4212, and at least a portion of the damping member 460 is received within the receiving groove 4212. The damping member 460 abuts against the groove wall of the receiving groove 4212 and the pin 414. The receiving groove 4212 communicates with the connecting hole 4211 to accommodate the damping member 460, making the connection of the damping member 460 more stable and less prone to displacement or loosening, thereby ensuring the consistency and stability of the damping effect. In addition, the abutment between the damping member 460 and the groove wall of the receiving groove 4212 and the pin 414 allows for more precise control of the relative rotation between the rotating member 420 and the first connecting member 410, further enhancing the damping effect.

[0168] For example, the shape of the receiving groove 4212 is adapted to the damping member 460 to prevent the damping member 460 from sliding within the receiving groove 4212.

[0169] For example, the receiving groove 4212 is located on the side of the connecting hole 4211 near the positioning post 424.

[0170] For example, along the extension direction of the center line of the connecting hole 4211, the receiving groove 4212 penetrates at least one side surface of the first rotating connection portion 421. This facilitates the installation of the damping member 460 between the pin 414 and the first rotating connection portion 421.

[0171] For example, along the extension direction of the center line of the connecting hole 4211, the receiving groove 4212 passes through both ends of the first rotating connecting part 421.

[0172] For example, the damping element 460 includes a spring. The spring is disposed between the pin 414 and the first rotating connection 421, and abuts against both the pin 414 and the first rotating connection 421. When the spring is in a compressed state, it has an initial elastic force. When the spring abuts against the pin 414, it applies the initial elastic force to the pin 414, forming a damping force for rotation between the first rotating connection 421 and the pin 414. Furthermore, the damping force is provided by the initial elastic force of the spring, which facilitates setting the magnitude of the initial elastic force and changing the damping force of the temple 300 opening and closing.

[0173] For example, the spring is a U-shaped piece, and its cross-section is U-shaped along the extension direction perpendicular to the center line of the connecting hole 4211. The two sides of the spring abut against the pin 414 and the groove wall of the receiving groove 4212, respectively, to provide damping force for the pin 414.

[0174] In some other examples, the damping element 460 can also be a rubber element.

[0175] Figure 8 for Figure 2 The diagram shows the wiring path of the hinge assembly provided. Figure 8 The arrows at the middle cabling channel indicate the cabling path.

[0176] like Figure 8 As shown, exemplarily, the first rotating connection portion 421 has a wiring channel 4213. The two ends of the wiring channel 4213 are angularly spaced around the first axis. Both ends of the wiring channel 4213 communicate with the space outside the rotating member 420. A flexible connector passes through the wiring channel 4213. The flexible connector, passing through the wiring channel 4213, is electrically connected to the first and second devices, realizing the electrical connection between the frame 200 of the smart glasses and the devices on the temples 300. Furthermore, it reduces exposed wiring, improves the overall aesthetics, makes the smart glasses look simpler, and reduces the risk of damage to the wiring during use.

[0177] For example, the wiring channel 4213 is an arc-shaped channel, which is arranged around the outside of the connection hole 4211 so that the arrangement of the wiring channel 4213 and the connection hole 4211 does not easily affect each other.

[0178] For example, the center of the wiring channel 4213 coincides with the first axis.

[0179] For example, the wiring channel 4213 is located in the portion of the first rotating connection 421 that faces away from the receiving groove 4212. This is to ensure that the arrangement of the wiring channel 4213 and the receiving groove 4212 does not easily affect each other.

[0180] For example, the substrate portion 411 of the first connector 410 has a wiring opening 4111, and the flexible connector passes through the wiring opening 4111 and the wiring channel 4213. The first and second devices between the temple 300 and the frame 200 are electrically connected through the flexible connector.

[0181] For example, the wiring port 4111 is located within the assembly space, one end of the wiring channel 4213 is connected to the assembly space, and the other end of the wiring channel 4213 is used to connect to the inner space of the temple 300. This allows the flexible connector to be hidden through the assembly space and the wiring channel 4213, reducing the exposure of the flexible connector and improving the overall aesthetics of the smart glasses.
